Understanding Hat Size Conversions

Hat Size can be confusing because each region uses a different sizing system.

• In the U.S. and UK, hat sizes are listed as fractions (like 7 1/8 or 7 3/8).
• In the Europe, they are measured in centimeters.

That's why we've built this hat size chart and conversion guide—to help you confidently buy from international brands without worrying about fit.

Hat Fit Guide

Once you know your hat size, the next step is making sure it fits the right way. Your hat should fit comfortably, not too tight or too loose. If it leaves a mark on your forehead, it is too small. If it slips down easily, it is too big.

If your size falls between two measurements, choose the larger one. You can use hat tape or a band inside to adjust the fit. Keep in mind that wool hats may stretch a little over time, while straw and cotton hats can shrink if they get wet.

Save or Share Your Results

Once you find your perfect hat size, you can download your results as a PDF or PNG. It's a simple way to keep your size handy whenever you shop online or visit a hat store.

You can also share your results with friends or on social media if you're helping someone else figure out their hat size in cm or inches.
